Description

Kitchen waste treatment equipment

Technical Field

The invention relates to the technical field of garbage treatment, in particular to kitchen garbage treatment equipment.

Background

The kitchen waste refers to waste generated in daily life and food processing, food service, unit meal supply and other activities of residents, and comprises abandoned vegetable leaves, leftovers, fruit peels, eggshells, tea leaves, shells, bones and the like, and the main sources of the kitchen waste are household kitchens, restaurants, dining halls, markets and other industries related to food processing. The kitchen waste contains extremely high moisture and organic matters, is easy to decay and generates stink. However, kitchen waste can be converted into new resources after being properly treated and processed, the characteristic of high organic matter content enables the kitchen waste to be used as fertilizer and feed after being strictly treated, biogas can also be generated to be used as fuel or power generation, and the grease part can be used for preparing biofuel.

At present, the domestic production process of the kitchen regenerated feed mainly adopts a biological method and a physical method. The biological method utilizes kitchen waste fermentation, uses the growth, reproduction and metabolism of microorganisms to accumulate useful thalli, enzyme and intermediates, and prepares the protein feed after drying. The physical method is to directly dehydrate the kitchen waste, dry and sterilize the kitchen waste, and crush the kitchen waste to prepare the feed.

The kitchen waste treatment method in the prior art comprises a crushing direct discharge method, a landfill method and a fertilizer treatment method. The crushing direct discharging method is generally a method of disposing a kitchen waste treatment device in a kitchen or the like, discharging crushed kitchen waste into a municipal sewer pipe network, mixing the kitchen waste with water, and discharging the mixture to a municipal sewage treatment system for harmless treatment. The landfill method is to send the kitchen waste and the common waste into a landfill site together for landfill treatment. At present, the landfill rate of the landfill method is on the decline trend, and even most countries forbid the kitchen waste from entering the landfill site for treatment. The fertilizer treatment method mainly comprises two methods of aerobic composting and anaerobic digestion. The aerobic composting process is that the extracellular enzyme secreted by aerobic microorganisms is used to decompose organic solids into soluble organic substances under aerobic conditions, and then the soluble organic substances are permeated into cells, and the whole composting process is realized through the metabolism of the microorganisms. Anaerobic digestion treatment of kitchen waste refers to that microorganisms decompose organic waste under specific anaerobic conditions, wherein carbon, hydrogen and oxygen are converted into methane and carbon dioxide, and elements such as nitrogen, phosphorus and potassium are remained in residues and are converted into a form which is easily absorbed and utilized by animals and plants.

However, in the above kitchen waste treatment methods, the smashing and direct discharging method is generally suitable for units with small kitchen waste amount, and the smashing equipment can not simultaneously smash different organic substances with dryness, wetness, softness and hardness, so that the method often causes the breeding of germs, mosquitos and mosquitos in urban sewers, causes disease transmission, can cause drainage pipe blockage, reduces the drainage capacity of the urban sewers, increases the load of the urban sewage treatment system, and inevitably causes secondary pollution.
